Abstract

The invention discloses " a kind of pueraria lobata is fresh to carry vacuum drying powder decoction pieces ", are primarily characterized in that：Pueraria lobata harvesting after, take advantage of it is fresh wash, be sliced, squeezing the juice, extracting, after extracting solution is condensed into clear cream, then be dried under vacuum to water content be less than 10%, crush, be sieved after be vacuum-packed.This prepared slice quality is stablized, and can both enter decoction decocting, can also directly enter pill, powder, tablet, capsule, is conducive to carry, Clinical practice is convenient.

Description

Pueraria lobata is fresh to carry vacuum drying powder decoction pieces

Technical field

The invention belongs to prepared slices of Chinese crude drugs technical fields, especially belong to the manufacture field of pueraria lobata medicine materical crude slice.

Background technology

Chinese medicament kudzu-vine root is legume pueraria lobataPueraria lobata (Willd.) dry root of Ohwi has expelling pathogenic factors from muscles and skin It brings down a fever, promotes the production of body fluid to quench thirst, the effect of promoting eruption, Shengyang Zhixie, clearing and activating the channels and collaterals, relieving alcoholism.It is usually used in fever caused by exogenous pathogens headache, rigid neck and back Bitterly, thirsty, it quenches one's thirst, measles without adequate eruption, hot dysentery, diarrhea, the treatment of dizziness and headache etc. is common a herb on tcm clinical practice. The processing method of traditional pueraria lobata is：After medicinal material is excavated, fresh-cut is taken advantage of into sheet or fritter, dry, packing, storage and transportation.Such medicine materical crude slice Bulky, Hygienic Standard is poor, is easy to make moist, is mildew, infested, being unfavorable for taking care of, storage and transportation cost are high.In addition, this The pueraria lobata prepared slice quality stability of sample is poor, and clinical efficacy is difficult to ensure, patient takes inconvenience, works slow.Therefore, exploitation is a kind of Stable quality is reliable, storage/transportation is at low cost, conducive to keeping, carrying and easy to use, rapid-action novel pueraria lobata medicine materical crude slice, gesture It must go.Pueraria lobata medicine materical crude slice currently on the market, other than traditional medicine materical crude slice, also two kinds of Ultramicro-powder medicine materical crude slice and concentrated granular medicine materical crude slice Form, but both using traditional medicine materical crude slice as raw material, quality is decided by the quality of traditional medicine materical crude slice, and ultramicro decoction piece cannot solve The problem of medicinal material pollutes；Concentrated granular can only extract water soluble ingredient.

Invention content

The invention discloses a kind of " pueraria lobata is fresh to carry vacuum drying powder decoction pieces ", are primarily characterized in that：It is harvested in pueraria lobata Afterwards, it cleans in time, removal impurity and the dis-medicinal part such as silt, cleans in taking advantage of using fresh herb tap water in 24 hours and be cut into 2 ~ 5mm Thick piece.The piece that this cuts is added in the water of 1 ~ 5 times of 50 ~ 70 DEG C of weight, impregnate and is constantly stirred 5 ~ 30 minutes, filtering, medicine Slag presses extracting juice.The water that 5 ~ 10 times of weight is added in the gained dregs of a decoction is boiled 10 ~ 30 minutes, is filtered while hot, the dregs of a decoction squeeze again Juice collects concoction.Merge above-mentioned concoction, crosses 60 ~ 100 mesh sieve, be concentrated under reduced pressure, temperature is 50 ~ 75 DEG C, and being concentrated into relative density is 1.15 ~ 1.25 clear cream.The clear cream of gained is dried under vacuum to water content at 60 ~ 80 DEG C and is less than 10%, is crushed, 60 mesh sieve is crossed, Vacuum packaging is to get finished product.Finished product medicine materical crude slice (C containing Puerarin₂₁H₂₀O₉) it is not less than 4.0%.Pueraria lobata medicine materical crude slice of the present invention is clinical general Usage amount is 1 ~ 5g, can both enter decoction decoction, take after mixing it with water, and also can directly enter in pill, powder, capsule and tablet, to significantly The convenience and compliance for improving Clinical practice, are conducive to the treatment of clinical acute disease.

The present invention solve traditional kudzuvine root drink piece is bulky, carrying cost is high, be unfavorable for keeping, easily mildew it is infested, defend The shortcomings such as the poor, unstable quality of raw condition, due to being to take advantage of fresh extraction, quality is drunk than ultramicro grinding medicine materical crude slice and concentrated granular Piece is more preferable.

Specific embodiment

It after pueraria lobata medicinal material is harvested, cleans, removes impurity and the dis-medicinal parts such as silt, using fresh herb is taken advantage of in 6 hours originally Water is cleaned, and is cut into the piece of 3mm thickness.This piece is added to 70 DEG C of pure water of 5 times of weight, is stirred 30 minutes, filtering, dregs of a decoction pressure Extracting juice.The pure water for adding 8 times of weight into the above-mentioned dregs of a decoction again is boiled 20 minutes and is extracted, filters while hot, the dregs of a decoction are again It squeezes the juice, collects concoction.Merge above-mentioned concoction, be concentrated under reduced pressure, temperature be set as 70 DEG C, be concentrated into relative density be 1.20 it is clear Cream.It is 8% that the clear cream of gained is dried under vacuum to water content at 80 DEG C, is crushed, and crosses 60 mesh sieve, is vacuum-packed to get finished product. Finished product medicine materical crude slice (C containing Puerarin₂₁H₂₀O₉) it is 4.5%.

Claims

1. a kind of pueraria lobata is fresh to carry vacuum drying powder decoction pieces, it is primarily characterized in that：It after pueraria lobata harvesting, cleans, removes in time The impurity such as silt and dis-medicinal part are added 1 ~ 5 times in the piece for taking advantage of using fresh herb tap water in 24 hours and cleaning and being cut into 2 ~ 5mm thickness The water that 50 ~ 70 DEG C of weight is impregnated and is constantly stirred 5 ~ 30 minutes, and filtering, dregs pressing takes juice；5 ~ 10 are added in the gained dregs of a decoction The water of times weight, boils 10 ~ 30 minutes, filters while hot, and the dregs of a decoction are squeezed the juice again, collects concoction；Merge above-mentioned concoction, crosses 60 ~ 100 Mesh sieves, and is concentrated under reduced pressure, and temperature is 50 ~ 75 DEG C, is concentrated into the clear cream that relative density is 1.15 ~ 1.25；By the clear cream of gained 60 ~ It is dried under vacuum to water content at 80 DEG C and is less than 10%, crushes, crosses 60 mesh sieve, is vacuum-packed to get finished product；Finished product medicine materical crude slice contains pueraria lobata Element (C₂₁H₂₀O₉) it is not less than 4.0%.
